Update: So we had a hard rain yesterday and the window did not leak. So it took replacing the full back window and the 3rd brake light. I the 3rd brake light had to be an updated part as they first to just wanted to silicone it in and I would not let them do that as that is not a factory fix. So I guess ram put out a new design for the 3rd brake light with an extra gasket at the top of the light. So if your 3rd brake light is leaking ask for the updated part.
